[Galaxy S I9000 Q&A, Help & Troubleshooting] zacharias.maladroit:
* well, actually newer revisions of that patch don't make use of ttys but of the task session

so basically it seems to create separate groups for each task (or program for simplicity's sake)

(source)

I'm also not sure if current Android kernel revisions use CFS at all ("Android versus Linux?")

laststufo has the autogroup patch included in his SO Kernel but I don't know how to measure its effect ... (whether it makes any difference)

* other options to improve interactivity would be to use Lennart Poettering's bash-approach (the script), like MaXo64 already posted: link

since Android uses Bourne Shell (sh) instead of BASH the script might need to be rewritten

* if it's stable enough on the SGS - yet another option would be to use Con Kolivas BFS
[Galaxy S I9000 Q&A, Help & Troubleshooting] zacharias.maladroit:
well, you could rewrite that script that it is run as a init-script (afaik in /system/init.d/ )

besides that:

there are stripped down (smaller) versions of bash 4.1* that are known to work on CM6 and the HTC Hero

so it should be a possibility to use that script on stock roms, too

if you can install busybox & root it, there also should be the possibility to install bash
[Galaxy S I9000 Q&A, Help & Troubleshooting] thunderteaser:
It seems you're very well informed, so thanks for the infos you're posting! :)

I'm not a coder, though, so I hope a kernel developer could pick this up and go for BFS. You said laststufo already implemented this patch in his kernel, so that's really good! We should just find a way of testing its effectiveness.

Yes, I've also seen bash shipping with some ROMs, so it's definitely possibile, though as I said before, I'm no coder...
[Galaxy S I9000 Q&A, Help & Troubleshooting] zacharias.maladroit:

It works very well, smooth & very accurate. I haven't experienced any issues with it.
[Atrix 4G Q&A, Help & Troubleshooting] dumasymptote:
Its much better than the captivate. I used Google Navigation to go somewhere the other day and it stayed locked pretty much the entire drive. It took a couple of minutes to get an exact lock (not that that was an issue) but after that it was pretty smooth.

GPS on Captivate was a joke, it never worked for me.
[Atrix 4G Q&A, Help & Troubleshooting] jeremy81:
It seems really accurate and fast. Google Maps/Navigation is smoother than ever on the Atrix. I received my Vehicle Dock yesterday and it's great. If you aren't using navigation the car home app shows your location on the map and the direction and even the speed you are traveling really accurately. Overall it seems even more reliable than either of my former phones the Dell Streak and Nexus One.

It was wonderful for me when I tested it at the AT&T store. It nearly immediately had a lock even being inside the store.
[Atrix 4G Q&A, Help & Troubleshooting] Rred:
Had a Captivate, and the major reason it went back was the poor GPS. Outdoors with a clear sky view it showed 30-35db signal readings, a full 10-20db less than an obsolete (two generations back) Deluo Earthmate usb "puck" gps sitting right next to it.

The Earthmate and a Nuvi both had signal and position, the Samsung kept saying the signals were too weak to use.

Switch to the Atrix: Outdoors, position within 10 feet (so it says) just like any commodity-grade GPS these days.

INDOORS, in a room with a steel shutter over the windows, it showed 30-35db signal strengths, equal or better to what the Cappy showed OUTDOORS with a full sky view.

No question in my mind, the Atrix has a commodity-grade GPS that works perfectly well. Whether they've done any tweaks or cheats in how it works, I don't know. I find the accuracy reading surprising, since that's pushing what a WAAS-enabled GPS would get and AFAIK no cell phones use WAAS GPS.

Checked position on Google Maps, and it is right on. I'm a HAPPY CAMPER and I'm not an easy customer to please.

Also, when the battery is fully charged on the Atrix? It doesn't wake up and ring and complain it needs to be unplugged. The Cappy tried to wake me up every night. Bad Cappy!

Now, if they'd only enable the FM radio...

Best gps i've seen on a phone. Very accurate and very fast
[Atrix 4G Q&A, Help & Troubleshooting] KryptosXLayer2:
Just came back from a 3.5 hour trip, one way, round trip (left last night and came back tonight), and the phone "lost" me twice - once was a typical SGS-style issue where it kicked me off the highway I was on and said I had to get back on at the upcoming exit, and the second time, for no reason whatsoever, the GPS kinda turned off.... I say "kinda" because it was still on when I checked my GPS widget but the GPS icon was gone from the notification bar. It wasn't searching for GPS, it just stopped showing up there. I turned it off and then back on, found me again in under 3 seconds.

Those were the ONLY issues I had in 7 hours of using the GPS during the last 24 hours. Tell me that isn't the best data you've ever heard on a cell phone's GPS unit??? :D :D :D
[Atrix 4G Q&A, Help & Troubleshooting] Rred:
By the way...the folks who own the GPS system, the DoD?

They issued warnings on both coasts several weeks ago, that "testing" could be expected to disrupt the GPS system in large areas. East coast, roughly NC down to Florida and west into the Gulf. If you are in that area, check online for details, the disruptions are minor but real, and they'll affect every GPS, not just one brand.<G>

I love the GPS! great accurate. Never had a device get a lock in such quick time!
[Atrix 4G Q&A, Help & Troubleshooting] oFUNGUSo:
i dont have the paid monthly GPS. mine locks on in about 30 seconds usually, to anywhere between 7 and 10 satelites, and gives me at best an accuracy of about 16 feet (testing using the GPS test app)

sometimes when attempting to use the navigation app, it refuses to load, not sure if GPS problem or app problem.

i just loaded it up sitting at my desk at work (navigation) and it took about 3 minutes for the app to say it was locked on to GPS.

really not sure what to make of that as its the first phone ive ever tried to use GPS on.
[Atrix 4G Q&A, Help & Troubleshooting] djdino:
That actually happened to me today.
[Atrix 4G Q&A, Help & Troubleshooting] mburris:
I can echo what most everyone else is saying: gps is fast and accurate on this device.

Previously I had a nexus one, and the gps on the atrix is just as good if not better.

I used it for about half an hour on a run with My Tracks, so by no means have I put it through a vigorous test, but from what I've seen, I've liked.
[Atrix 4G Q&A, Help & Troubleshooting] DarkSi08:
That's unusually poor performance compared to what I've been seeing. I get a 16ft lock within 2-3 seconds while standing in my basement. Open up GPSTest, 7+ satellites in view immediately, lock immediately thereafter. That seems to be the general consensus on the GPS on this phone.

And, for the record, I live in NC, one of the areas affected by the DoD GPS outage. That outage was 1/22-2/22, I believe, so it has already ended. :)
[Atrix 4G Q&A, Help & Troubleshooting] Kazeari:

Sitting in a waiting room today, presumably wood frame building, upper floor, one window with blinds over it...and the Atrix was getting signal levels around 22. And locking in position very nicely at that low level, half of what the Cappy needed to find itself!

ok, so after updating maps, navigation does lock on, although not very quick. gps test is still rather slow, and accurate only to about 16 feet......but testing out the navigation on my way home from work, it worked perfectly and accruate so i guess i have no complaints
[Atrix 4G Q&A, Help & Troubleshooting] eatkabab:
The atrix has the quickest and most accurate lock of any phone GPS I've ever used.

After the initial few uses, the thing gets a lock in seconds. Indoors/outdoors doesn't matter. truly a godsend (my last phone was the broke ass captivate...)

Others experience my vary but I'd be hard pressed to believe it varies too much.
[Atrix 4G Q&A, Help & Troubleshooting] Rred:
"and accurate only to about 16 feet......"

For a civilian GPS that is not WAAS-enabled, 10-meter accuracy (i.e. 32-33 feet) is all you can really expect on any regular basis. That's a limit of the GPS system--not your GPS.

16 feet is better than you should expect from a cell phone. Honest.

Besides that it - happened when I was playing a game too. Just a few minutes ago
[Atrix 4G Q&A, Help & Troubleshooting] elementaldragon:
I'm assuming you're all talking about the ACTUAL GPS.... not just using the free triangulation-y bits you get if you normally try to find your location? I haven't tried either on the Atrix yet as i don't see the point in paying for GPS services for a phone, ESPECIALLY monthly when you can buy a little Garmin and use that while only paying for it once. Nor have i really wandered around staring at my Atrix to see if it picked up on me rather well with triangulation. I know my iPhone 4 was quite good at that though...
[Atrix 4G Q&A, Help & Troubleshooting] Squeak22:
You realize that it uses the GPS when you go to the map app. And you don't have to pay anything if you use Google maps/navigation.

When it has a huge blue circle, its triangulating. When it locks you get the single point/arrow.

I can't count the number of times my inc has lost me or jumped of track while navigating because I honestly don't recall it happening. Granted I don't do a lot of city driving but this also means that the device us getting no triangulation assistance from cell towers and relies entirely on the gps ability of the unit.

I understand some phones with Agps has problems getting a fix when there is no cell tower signal. Is this a problem on the Atrix?
[Atrix 4G Q&A, Help & Troubleshooting] KaLiBLeeK:
I'd been having issues with RunKeeper the past few days, and I saw somebody mention that they never use the "Use Wireless Networks" option, so I figured I'd give that a try; ever since, my GPS has been perfect, and any apps that use GPS seem to lock on almost immediately.
[Atrix 4G Q&A, Help & Troubleshooting] Rred:
"I understand some phones with AGPS has problems getting a fix when there is no cell tower signal. Is this a problem on the Atrix?" All A-GPS work in the same basic ways. The Atrix will have the same problems, if it is using the same system and that system is having the same problems. If your Atrix needs to use the network and the network isn't there...it can't work, can it? That's not a problem in the phone.

But since the Atrix GPS works rather robustly without needing A-GPS, it is not likely to be a problem. As compared to something like a Captivate, which needs the assistance modes rather badly because, apparently, the GPS in it is defective.

A-GPS using the cell towers takes more than just a signal from them. The phone has to send data to them, then two preferably three towers have to take that signal, cross-compare it with each other, process it in the cell system, and send that data back to the cell phone. There are different implementations but that's the basis of them all.

So from the cellular company's point of view, they'd really rather not tie up their equipment doing A-GPS unless you're paying for it (with a nav system). They have every incentive to program the phone NOT to use the towers for position, unless it has to.

A new phone typically has GPS plus 3 A-GPS modes, and program control over the sequence and use of them. Older phones in the US (but not the rest of the world) often had only "half" a GPS chip in them, and required use of the cellular system, so you would be forced into buying the use of nav services.

And having said that...does anyone know if there's a secret Moto Menu that allows us to set the control options for the Atrix GPS? To use or ignore Skyhook and web servers for A-GPS modes?
